Back then when they were transforming the IDOLM@STER IP into all sorts of different media, including a Korean drama because why not? The drama itself played out exactly as you may expect and the first episode gave the necessary impression to set the expectations going forward. The cast members consisted mostly of idols so you may expect varied degrees of on-screen presence and performance. The drama explored one of the girls stories every 1-2 episodes but these were extremely predictable and bland, offering no variety, theming or appeal. You would expect this type of show to be much shorter but for some reason they went for full length, I guess they had the IDOLM@STER budget.
